D2801R503R3P
D2801R503R3P is HIGH RELIABILITY RADIATION HARDENED LOW POWER DC-DC CONVERTER manufactured by International Rectifier.
Description
D2801R503R3P is part of the International Rectifier Hi Rel family of products. The D-Series of DC-DC converters are low power radiation hardened, high reliability devices designed for radiation environments such as those encountered by geostationary earth orbit satellites, deep space probes and munication systems. Features include small size, high efficiency, low weight and a high tolerance to total ionizing dose, single event effects, and environmental stresses such as temperature extremes, mechanical shock, and vibration. All ponents are fully de-rated to meet the requirements of EEEINST-002. Extensive documentation including worst case analysis, radiation susceptibility, thermal analysis, stress analysis, and reliability analysis are available.
The D-Series converters have two outputs, each is independently regulated. The outputs can be both positive or one positive and one negative. The D-Series converters incorporate a fixed frequency flyback power stage topology and internal EMI filter. The converters include an enhanced input EMI filter that meets most major satellite power buses. The converters can be remotely turned on and off via an Inhibit pin. Additional Inhibit pins are also provided to control the outputs individually. This feature facilitates turn-on outputs sequencing if desired. Each converter is encased in a cold rolled steel hermetic package. The package measures 1.80"L x 1.40"W x 0.42"H and weighs less than 55 grams. The package utilizes rugged ceramic feed-through copper core pins and is hermetically sealed using parallel seam welding. Two package options are available. Please refer to page 8 for I/O configurations.
Environmental screening includes temperature cycling, constant acceleration, fine and gross leak, and burn-in as specified by MIL-PRF-38534 for class H hybrids.
Non-flight versions of the D-Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom...
